PROCESS FOR TREATING GASES OBTAINED BY COAL GASIFICATION, RESIDUE GASIFICATION, REFUSE GASIFICATION OR OIL GASIFICATION

摘要

The invention relates to a process for the treatment of synthesis gas or fuel gas obtained by coal gasification, residue gasification, waste gasification or oil gasification, in which the gas stream obtained by gasification, which contains reducing and possibly inert gases, is treated for the removal of sulfur, optionally after separation of the desired product synthesis or fuel gas, is subsequently hydrogenated, the sulfur compounds still present in the gas stream thereby being converted to hydrogen sulfide, the hydrogen sulfide is removed from the gas stream by adsorption or absorption on a solid or liquid sorbent and the loaded sorbent is supplied to the coal, residues, waste or oil to be gasified.
